The Significance of Rex Tillerson

Secretary of State Rex Tillerson has had a conflicted tenure to this point. Love or hate President Donald Trump's foreign policy, it won't be controversial to say that the U.S. Department of State has not operated in its standard way during Tillerson's first year as top diplomat.

We caught up with Aaron David Miller for some perspective. Miller, an occasional contributor to RealClearWorld, has worked for six secretaries of state. He puts Tillerson's first year into context and brings us back to the basics of the Department of State's function in the greater scope of U.S. foreign policy.
